The investigation and measurement of the radon gas working level inside buildings in Rafsanjan

Radon gas and its daughters are radioactive and radiate alpha particles with high energy. These particles can cause DNA damage, which may or may not be properly repaired. Also, if these particles get into the lungs for a long period of time, they may damage the lungs' inner tissue. This is one of the most important causes of lung cancer after smoking. This paper presents a report on the measurement of radon concentration by means of a radon working level meter, based on the Environmental Protection Agency (EPA) conditions in 68 houses, which cover 0.23% of the total houses in Rafsanjan city. The results show 0.35 mWL and 33.43 mWL as the minimum and maximum concentrations, respectively. Additionally, the concentration in 5.12% of the houses is more than the acceptable value.

As the saying goes, clothes can make people more beautiful, in fact, the house is the same, when you buy a house, and give it a beautiful coat, can improve the quality of life, living in the house for a long time, re decoration, the old house and get a new life. However, the decoration pollution problem has become a lot of people's heart disease. Today we are going to talk about the decoration process, in addition to formaldehyde we are familiar with, what are the toxic and harmful gases.
In the national standards...

1.New buildings: how can engineers and architects predict radon levelsTesting is the only way to know a building’s radon levels. At present, there are no reliable, easily applied and inexpensive methods that could conclusively identify problem sites and predict if a new building will have high indoor radon levels. There are a lot of factors that cause elevated indoor radon concentration. It is thus impossible correlating the results of radon evaluation tests of soils at a building site with consequent...

Water samples collected from different sources were analysed for radon concentrations in order to evaluate the health effect associated with radon in water. The radon concentrations were in the range of 3.56–98.57, 0.88–25.49, 0.73–1.35 and 0.24–1.03 Bq.L−1 for borehole, well, packaged and utility water, respectively. Samples from boreholes had the highest radon concentrations with about 67% being higher than the threshold value of 11.1 Bq.L−1 recommended by the USEPA. The mean annual effective dose (AED) due to...
